LEWIS M. RUMSEY, OF ST. LOUIS, MISSOURI.

CHAIN-PUMP BUCKET.

SPECIFICATION forming part of Letters Patent No. 271,522,0lated January 30, 1883, Application filed September 19, 1882. (No model.)

To all whom it may concern I Be it known that I, LEwIs M. RUMsEY, a citizen of the United States, residing at St. Louis, in the county of St. Louis and State of Missouri, have invented certain new and useful Improvements in Chain-Pump Buckets, of which the following is a specification, reference being had therein to the accompanying drawings.

' The invention consists in certain details of construction of the rubber or other elastic button and. the looped metal core or casting carrying the same, these two parts comprising the bucket, so that it will not permit air or water to pass down, by, or through it while passing up the pump-tube in the operation of elevating the water, but as soon 'as the pumping ceases allows the water to pass through the bucket back into the well, leaving the tube free of water.

Referring to the drawings, Figure 1 is a perspective view of the metal core. vertical section of the complete bucket, and Fig. 3 is a plan of the rubber button.

The metal core A is constructed with the usual eyes, E E, at each end to receivethe links of the chain. At the bottom of the upper loop I provide the annular flange D to hold the rubber button in position. What may be called the shank portion of this metal core or, in other words, the portion just below the flange Dis made substantially bell-shaped, terminating in a flange which is of somewhat smaller diameter than the internal portion of the bottom of the rubber button A. Entirely around this bottom flanged part is an annular groove, 0, and radiating therefrom are a suitable number of small grooves, c, which extend to the edge or periphery of the flange.

The button A is substantially hemispherical, with a central hole in its top or dome portion of a size corresponding with the top of the shank and less than the diameter of the flange D, so that in operation it will not be forced over it. I holes through its top in a vertical direction, or nearly so, and they are so arranged that when the two parts of the bucket are in position the holes will be coincident with the annular Fig. 2 is a The button A is provided with groove (3. Any suitable number of holes may be used, and I make them through the rubber in such a manner that the bell-shaped flange of the core will cover the holes while the bucket is moving up the tube. hen theupward motion ceases and the bucket remains stationary the weight of the column of water above the bucket is transferred to the metal flange, supporting the bucket by pressing through-the holes. The weight of the chain below the bucket draws down on the casting, while the peculiar construction of the rubber forming the bucket makes the edges adhere to the pump-tube, preventing it from taking the downward motion of the chain and metal casting carrying the rubber bucket. It will be seen that this will lift the rubber from the metal flange, covering the holes in the rubber and sealing them while moving up the tube, thus allowing the water to run back into the well and saving the tube from damage by freezing water that would otherwise be held therein.

In order to facilitate the draining process, I cast a groove in the metal flange of the casting carrying the button, so that the groove will be directly under the drain-holes made through the rubber button. I also cut one or more grooves of about the same depth extending from this circular groove to the edge of the casting. This facilitates the water supporting the rubber and casting and its passagefrom above the bucket through the holes and grooves down the tube into the well and water below.

I am aware of the rubber bucket made by W. (J. Barker, with a hole in the edge of the bucket which is always open, destroying its utility, and I make no claim to such a device.

I am also aware of patent to Henderson, No. 161,881, and do not claim any thing covered by said patent.

hat I claim as new, and desire to secure by Letters Patent, is-

1. A bucket for chain-pumps, consisting of a metal core, with theusual loops or eyes, and a bell-shaped shank having an annular groove, an intersecting radial groove on its lower flanged portion, and a rubber or other elastic or button, substantially as set forth.

3. In a chain-pump bucket, 21. metal core havlo ing loops or eyes at its ends, a top flange, D,

and bottom flange with the annular groove 0 and radial grooves 0 o, as and for the purpose set forth.

In testimony whereof I affix my signature in presence ottwo witnesses.
